HOPKINSVILLE, Ky. -- A trucker from Hopkinsville, Ky., is being questioned after a disturbing note turned up at a rest stop.

A maintenance worker found the note taped to a mirror at the facility on Interstate 65 southbound in Bullitt County, Ky. The letter claimed to be written by an Indiana boy who said he and his sister had been abducted by a truck driver.

Police have identified a truck driver who was in the area at the time. All authorities will say is that he's from Hopkinsville and that they're attempting to talk to him. They're also asking the public for help.

"If anyone has seen anything suspicious, maybe involving a man and a woman along with a truck driver, maybe, or if anyone has seen anything suspicious at the rest area in Bullitt County, contact the Indiana State Police, Kentucky State Police or Bullitt County Sheriff's Department," said Det. Scotty Mcgaha of the Bullitt County Sheriff's Department.

Investigators said there's a chance this could be a hoax, but they're treating it seriously for now.
